New Revision: 240189
URL: http://llvm.org/viewvc/llvm-project?rev=240189&view=rev
Log:
Stop moving attributes off of a block literal's decl specifiers.
These usually apply to the return type. At one point this was necessary to
get some of them to apply to the entire block, but it appears that's working
anyway (see block-return.c).
